Where Lillooet’s numbers come from
Averages over 30 years, not a forecast.
- Normals: Environment and Climate Change Canada’s 1991–2020 normals, Clinton: the nearest of its locations with every month’s temperatures.
- Other locations: ECCC blanks a month that fails its completeness rule, so the precipitation or snowfall here comes from the next location with all twelve months.
- Comparisons: all Canadian places of 2,500 or more except city totals and reserves, each read the same way.
- Not on this page: snowfall (no location within 100 km publishes a full year of it), sunshine (none for 1991–2020) and an altitude correction.
